The gdb install target installs dynamic versions of libbfd and libopcode, accidentally overwriting the binutils provided versions (gdb itself links against the bundled static ones to avoid version problems, so the dynamic ones are un-needed). Prevent the installation by using the '--disable-install-libbfd' configure option.
